1) “Walking With Dinosaurs,” 8-10 p.m., PBS. Back in 1999, this drew praise and enthusiasm. Now it’s been rebooted beautifully, in a three-night series mixing special effects, animatronics and great filming. We see scientists finding bones … then get stories imagining those creatures. This starts (shown here) with a baby triceratops and a 13-foot-high tyrannosaurus.
2) Basketball, 8:30 p.m. ET, ABC, with pre-game at 8. After two games in Indiana, action returns to Oklahoma City for the fifth game of the best-of-seven championship. If needed, there will be games Thursday and Sunday.
3) “Sally,” 9 p.m., National Geographic. This profiles Sally Ride, the first American woman in space. She flew a second mission and played a key role in the commission that probed the Challenger disaster. She was also the first known LGBT person in space, registering her longtime domestic partnership shortly before her death, at 61, in 2012.
4) More non-fiction. At 8 p.m., History reruns two hours of “The West.” The first views “the Robin Hood of the West”; the second looks at the rush to Kansas, deciding if it would be a slave state. At 10, PBS reruns a superb hour that puts David Attenborough in a museum with special-effects dinosaurs.
5) “Art Detectives,” www.acorn.tv. In its third week, the show already veers far from its theme. Except for a tiny speck near the end, this story has virtually nothing to do with art. Still, it’s a fairly interesting story, set at a rock-music studio, with Stephen Moyer leading the investigation.
